10.3 DSBGA Mounting

The DSBGA package requires specific mounting techniques, which are detailed in TI Application Note DSBGA

Wafer Level Chip Scale PackageSNVA009.

For best results during assembly, alignment ordinals on the PC board may be used to facilitate placement of the

DSBGA device.

10.4 DSBGA Light Sensitivity

Exposing the DSBGA device to direct light may affect the operation of the device. Light sources, such as halogen

lamps, can affect electrical performance, if placed in close proximity to the device.

Light with wavelengths in the infra-red portion of the spectrum is the most detrimental, and so, fluorescent

lighting used inside most buildings, has little or no effect on performance.
